v1.1.2 Improvements and fixes — Towers Heritage Steam update #1421544

Improvements : Changed the sounds of projectiles ice, poison, holy, sniper and of the bunker. Technologies and combat abiliities are better explained when you hover them in a game. The game tells you exactly what it does, and what numerical values are used. Technologies prices have increased, as well as their cost relative to their level. In the panel to see the incoming enemies, you can hover the picture of an enemy to see its characteristics, instead of clicking on it like before. Fixes : In a "free maze" level, the path of the enemies (the green-ish cylinder) is better updated when you want to construct towers. Aura towers were buggy. Now they work as expected, and they've been balanced. The audio manager could be satured and play loudly a sound. It doesn't do that anymore, but can still be improved.
